IMPROVEMENT IN WATER-WH EELS.

Specication forming part of Letters Patent No. 8,429, dated October 14, 1851.

Fig. 2 is a vertical and transverse section ofv the same.

A in the said drawings represents the wheel; I3, the ring of directing-passages; C, the flume; D, the vertical axle, and E the supportingframe oi' the wheel. The ring of directingpassages is composed of a series of curved passages a c c, arranged in a circle and leading out of a common central fiume O, whose bottom is represented at b and as having the axle of the wheel passed through it. The wheel is composed of a horizontal circular disk c, in which is arranged vertically and in a circle a series of buckets f f f, &c., as seen in Fig. 2, these buckets being covered by a circular ring e c, which is disposed on them and parallel to the disk c.

Between each two buckets and between the front face of the back part of one of them and the rear face of such side of the others of them and about midway between the same I arrange a vertical and curved partition d, so as to make, as it were, two passages g and h, leading into each bucket, each of the said partitions being made to extend inward beyond the said two buckets (or the circle in which their inner edges are situated) a distance toward the ring ot' discharging-mouths, as seen at z'.

The direction in which the wheel revolves is denoted by the arrow O.

The water in rushing out of any one of the discharging-passages a a, &c., will first iiow into the passage h of a bucket, as denoted by the arrow 7.o. It strikes into the buckets, as denoted by the arrows lm, and drives the air which may be in the bucket out through the passage g and around the inner end of the bucket, as denoted by the arrow fn, or through an air passage p and into the bucket in rear, where it can freely fiow away.V The Water acting on a wheel constructed in such a manner meets with very little obstruction from air in the buckets, and is enabled in consequence thereof to operate without any material loss of power, which would otherwise be likely to be produced by the retention of air in its buckets.

What I claim as my improvement is The combination of the curved partition CZ and the air space or passage p with each two buckets and for the purpose of causing the escape of air from the bucket into the next 011e in rear, all substantially as speciiied.

In testimony whereof I have hereto set my signature this 11th day of August, A. D. 1851.
